Citing unnamed sources, Politico and Reuters reported on Sunday night that Trump had decided to end the DACA, a program created by the Obama administration in 2012 and that protects nearly 800,000 young undocumented immigrants from deportation.

Reuters, citing sources familiar with the situation, said that Trump will give Congress six months to craft a bill to replace DACA. But a senior White House aide told Politico that John Kelly, Trump's chief of staff, “thinks Congress should’ve gotten its act together a lot longer ago.”

"For all the members of Congress over the past 5 years who said DACA should've been done "legislatively" here's your chance." tweeted Joaquin Castro, D-Tex., closing with the hashtag "DefendDACA."

Ending the DACA would make good on a campaign promise and is sure to please Trump's supporters. The move would also terrify DREAMers — immigrants illegally brought to the United States as children — whose lives will be upended.
